    x86/PCI: amd: Kill misleading message about enablement of IO access to PCI ECS] · ca3671a8
    Andreas Herrmann authored
    Commit 24d9b70b (x86: Use PCI method
    for enabling AMD extended config space before MSR method) added a
    message when IO access to PCI ECS was enabled via access to the NB_CFG
    PCI register.  This can lead to a bogus message like
    
    [    0.365177] Extended Config Space enabled on 0 nodes
    
    which is misleading because IO ECS access is subsequently enabled for
    AMD CPUs (that support this) by modifying the corresponding NB_CFG
    MSR.
    
    Furthermore it's not "Extended Config Space" that is enabled by this
    register setting. It's the IO access that is enabled for extended
    configruation space.
    
    IMHO the ambiguous message needs to be cancelled.
